Re: building with nghttp2 + ssl

Hello,

Forgive me if I am missing something here but was the removal of NPN support intentional? The following changes seem to have done that for me: https://github.com/bagder/curl/commit/e42e3a4facfca971b5e09e8351312946ccb25e79#diff-7dafef8d70eee3940c9184e4e4e93448 and https://github.com/bagder/curl/commit/357a15a6492ac0496abe952fae70aef7da017158#diff-7dafef8d70eee3940c9184e4e4e93448

I am using Centos 7 with the up-to-date official OpenSSL (open-1.0.1e-43.el7_0.6.x86_64), which unfortunately does not have ALPN support.

nghttp2 supports NPN or ALPN, therefore in my environment I have nghttp2 built supporting only NPN. In the past I have successfully built curl with HTTP/2 support using my NPN-only nghttp2.

Since the above changes, I can no longer build curl, receiving the error message "error http2 builds require OpenSSL with ALPN support!".

Regards
Lucas
